As a member of the injured mans family, I am rejoicing that the Harford County Sheriff's Office has done such a wonderful job handling this entire situation. There have been many prayers offered on behalf of my family and the Sheriff's Office. We are so grateful to God for His mercy and grace.

So glad to heat praise for the HCSO for once! My father (a captain for HCSO) was up all night last night after his regular shift during the day in efforts to put this neighborhood at ease. So glad their efforts paid off so everyone can enjoy the Holidays!

Thank God! Atleast now maybe the family will be able to sleep at night. The supposed suspect has quite the arrest record. I have to be politically correct!! LOL!! I know the family that were his victim. I hope their minds are a bit at ease and attempted murder is the right charge!!

This guy is a hopeless drug addicted loser. He was trying to steal others hard earned belongings to support his and his girlfreind Casey's drug habit.

They should of denied him bail.. when he gets out on bond until his court date he will still live right down the street who's to say he won't do something stupid again....

Scumbags like that don't deserve bail. Let him sober up in jail.

Address on oxford ?

No doubt what he did was wrong. All these hateful remarks are not going make it better. Stop name dropping until you get the facts right. This is not the first time someone on drugs has done something terrible. Thoughts and prayers for everyone involved.

Thank God that our Sheriff's department worked so diligently with the community and were able to arrest the guy. I am a neighbor of the victim and hope that his arrest will bring some sort of comfort to them knowing he is in jail. Although, I can't imagine how shaken up they are. The guy does not deserve to be out on bail. I have prayed for my neighbors and the hopes that they would catch this guy. God has spoken!

Has anyone been to the new Sonic in Bel Air? They have great milk shakes!

The suspect broke into my car last week but police couldn't find evidence to arrest him. This is bittersweet.

Spiderman,

Thats what scumbags do. Hopefully they can link his finger prints!

Looks like he had one hell of a buzz going when that mugshot was snapped.

Anyone else find the irony in his shirt? "Fight for a better world" lol

You're telling people not to name drop when you're the only one that's done that, concerned citizen!

Ashley, I noticed that as well.

There are 2 Concerned Citizens on here!

This guy is wearing a 'fight for a better world' shirt. It's too bad the homeowner didn't have a shotgun with some birdshot. The world would be significantly better if we didn't have to pay to house and feed this thug.

Check out his FB pictures. Amazing what drugs can do over the course of a year or two. Looked like a happpy, healthy kid. Huge difference from his junkie mugshot.

Yes it's under Sean Keller. Yes he is a complete dick, I've known him a while. It was only a matter of time until this happened.

If you know Sean, you'd know this was about drugs.

I can't believe you have all made this a social network to bash people. This is NOT a place to poste peoples names and addresses. Many lives have been afftected here and they need a little respect and kind words, Not harsh nasty words. Ever think that maybe both families need prayers! Even the person that did the crime should receive prayers. NO one on here knows the entire story and therefore should keep their personal comments to themself!
Let me be the first to offer my prayers to EVERYONE involved!

Cool, pray for him when he bails out, breaks into your house and stabs you. Idiot.

Peter Parker I know who you really are muahahaha

And who might you be?

Hopefully he looks like that because the homeowner beat his head in!! He deserves it! I like his record. Dwi and additional thefts in 2011 and 2012! Bye bye! Bel Air can feel a little bit safer because your babies/family aren't getting killed because he chooses to drive drunk and homeowners can sleep more soundly because he's locked up. Good influence for the younger siblings.

Peter Parker - I will. Your the idiot!

Knowing sean and have since I was 10 years old..he was high. He was at darkhorse the night before high with another one of our friends..he's always done dumb things. He lives a couple door down from me and the cops found drugs in the house. They have been in & out yesterday and this morning. This was about him being extrenely high and stupid.

i was in the marines and served in afghanistan. ive been cleaning my gun to perfection ever since that morning. he lucked out not breaking in my home down the street from him. the police catching him may have saved his life.

Can't call people an idiot when you can't get the correct "you're."

Lol I love that drug addicts think its ok to break the law because they are high.... His parents should be really proud of what they raised...lol

I've known him since high school. Piece of shit then, still a piece of shit now.

THANK GOD! I've been waiting for him to be locked up for good...just the sight of him has made me sick since high school.

Why did the police not mention he had a gun. I have lived on oxford for twenty years and in the past couple of years it has been getting bad. Last year at this time there was a driveby shooting at the same row of houses as he lived in. The police did not report it as a driveby because no persons or property was shot and said the shooters were just trying to scare someone. There have been a lot of attempted burglaries and burglaries here in Thomas run and tudor manor and it is said to be kids that are pillheads from these neighborhoods. Like scottyb said time to clean your guns!!!

you cant polish a terd. only a matter of time before this or something worse happened. one less to worry about in the neighborhood. doesnt mean we shouldnt all still up security and keep an eye out on eachother!

My thoughts exactly scottyb. We should all keep an eye out for eachother and report any thing suspicious

The only victim here is Mr. Certeza and the rest of America's youth. If the younger generation had legitimate job opportunities, they wouldn't be forced to commit crimes just to feed themselves. This would not have happened if we elected Mitt Romney president. Along with [keeppersonal] I will be praying especially hard for Sean.

You people sound like a bunch of uneducated gypsies at a witch hunt. So easy to judge. It is terrible what happen but obviously you people need something better to do with your time.

Mort feldstein.... After reading your comment you must of been hitting the crack pipe with him.. the only victims are the man that got stabbed and all the neighbors that don't feel safe any longer..

Mort Feldstein, seriously? I voted Romney too, but come on, that's ridiculous. I'm sure the kid didn't break into the home for food money or to eat! I knew plenty of families growing up that had nothing....yet they didn't steal, burglarize or injure innocent people. They took what jobs they could get, were grateful for them and worked their rears off to to feed their families.

Witch hunt? If that's what it takes to keep our lovely neighborhood & the families that live here safe, I'm all for it.

Speaking of such, those of us in the community should start holding community crime watch meetings. Zero tolerance for criminal activity.

I am a neighbor and crime victim of Sean's. He was found guilty of trespassing on my property (my back deck @ 2am), God only knows what he was doing there. My 12 year old daughter hasn't slept in her own bed since that night...so Mort please explain to me who the real victim here is. Sean is a grown man, he chose his own path.

Why have all the papers left out the part about the assault rifle......... Is it the sheriffs department not giving out the information or is it the newspapers softning the news to make Bel-Air a more appealing place to live

Lol...I never said it was ok. You were saying this wasn't about drugs but it was. That's all sean is...a drug addict. I've hated him since I met him! So try not jumping to conclusions please :) he was made fun of constantly by all of his "friends" no one liked him and never has liked him. He assulted a few people I know & was accused multiple times of rape in highschool. I was just saying this does not come as a shock to me because we have always known he is a nutcase crazy person. He should have been in jail a long time ago. This is not the first "episode" this person has had.

And mort you are ignorant. He is not a victim...I don't even get how you can possibly say that...

I've known Sean for a really long time. His real name is Sean Michael Certeza but he goes by Sean Keller. He is a horrible person. He has done tons of bad stuff to people from steal to making up rumors to vandalism. His mom is a very sweet lady tho so as long as he is locked up don't be scared to live in that neighborhood. Sean has TONS of stuff on his record and has been a drug dealer in the past. He's a crazy crazy guy who I thought had changed but apparently has not. I was a victim of one of his vandalism attacks. Which I can't prove but everything leads to it being him. He deserves whatever is coming his way!!

Agreed 100 percent sarah!!! There are still a couple people in the neighborhood I worry about though! I am soo happy to hear sean is in jail though. There is another person living in the neighborhood that has been in and out of jail for years. The last time he went to jail it was because he threw a girl down a flight of stairs, beat her, and then choked her. People are disgusting. Its very sad..because thomas run used to be a nice place to hang out with our friends after school..now it is just scary. My step mom and my dads cars have been broken into multiple times. We had to get a security system. it literally beeps when any door is opened & tells us what door has been opened and stores everything. I would recommend everyone doing that because I don't think this will all stop.

A friendly reminder when leaving comments: remember to abide by Patch terms of use, you can find them here: http://belair.patch.com/terms. I will be reviewing comments for violations.

Thanks everyone for all the info to this crime as well as past crime on Oxford.. I def will keep a closer eye out now..I knew in the past there were some issues with crime but did not realize there were so many victims on our street that fell "victim" to this guy and others..I myself have really not fell "victim" to any of this BUT I do get tired of the constant late night loitering and noise....thanks again for the info !

Ironic that this is his favorite quote...Favorite Quotes
GOOD JUDGMENT COMES FROM EXPERIENCE AND EXPERIENCE COMES FROM BAD JUDGMENT. He must have lots of experience!!

This is a sad thing. The guy is young and needs some help, obviously. It's sad this is his wake up call. I feel sympathy for the victims, as well as for Sean's parents. I can't imagine the sorrow and embarrassment they must feel. For those throwing out names and harsh judgements, i feel bad for you too. Wait until you or someone you know makes a mistake, Karma is harsh.

I agree.. Unless you have walked in someone's shoes, you can't possibly know the storms we face.

ship this punk back to Edgewood

I'm old enough to remember when Edgewood was a great place to buy a home and raise a family.

the kid lives with his parents. i assure you he wasnt doing it for food to eat.

The ppl talking about judgement didnt know sean. He was a loser..he lives with him mommy & always has. He is NOT fro edgewood ? Lol...He ALWays caused problems! He's not mentally ill he is just on a tons of drugs that make his craziness a million times worse. Maybe you should be more cautious of who you decide to not pass your judgement on because he could end up robbing and stabbing you....

RU Serious, the firearm he had was a small caliber handgun. And yes the police and paper downplay crimes or not release all information so Bel Air does not seem that bad. Just look at the crime report and you will see. Remember harford county citizens should be aware of the seriousness of the crimes committed so we are aware of what us happening here. You should check the HCSO website to see if what upcoming events they have. There should be one coming up In jarrettsvile with Sheriff Bane.

You know, these drugs that are causing an epidemic these days are opiates---most all are doctor prescribed LEGAL drugs. This epidemic of break-ins goes along with the epidemic of prescription opiates that have flooded our nation in the last decade. No excuse, his choice, but opiate addicts do rob you blind!

It is becoming clear to me that this guy is not getting the message by traditional enforcement. Someone needs to increase the intensity of the message to Mr. Certeza. Perhaps a few more whacks with a baseball bat are in order.

Ithii guess some people think we shouldn't judge a person who runs around a neighborhood being a hoodlum freak...however; get used to me judging people. Everyone does it! He's a weirdo and always has been and always will be. && I'm not judging if I know the freak! This has been a long time coming but his mom always bailed him out of hisscrew ups and now she can't because she would most likely lose her house. And any gun can kill someone...how can u say its just a gun??

Clearly his law breaking activity is displaying increasing violence. He will stop when he either kills someone or he is killed in the process of his problem.

I know even a .22 or .25 can kill very easily, it does not matter the caliber of handgun just wanted to let everyone know it was not an assault rifle I have been into target and competition shooting for 23 years and I am aware of firearm ballistics. There needs to be stiffer penalties for criminal that use firearms in the commission of a crime and people need to make sure the firearms they own are secured and the having propper training and practice regularly. A firearm is just as dangerous to the owner is they are not trained on how to use it.

Lolol great read on the comments section. From everyone going HAM on this kid to the war lesson i just got about smaller caliber guns. All signs point to he should be locked up and helped. Seems safer for society for him to seek some sort of (forced) reform.

Sean also has a habit of vadalism. He enjoys cutting open the tops of convertibles and stealing the contents! My friend knows this first hand! I hope he rots!

I am so frustrated I spent my time reading these comments! Won't do this again

Sean is just part of the drug problem, he deserves about 20 years in the pokey and will probably get it....how bout all the "adults" who doctor shop and use the black market to get their pills, difference between them and Sean is they have the money and keep the facade up of a solid citizen, but there as hooked on drugs as Sean. Huge pill problem in our society now with the so called adults....probably a couple on this forum who post have a secret pill problem.....just saying.....its prevalent at all levels of society.

Sean was NOT let down by ANYONE in his community, county or state - FYI; you cannot help someone who is unwilling to help themselves. NO ONE will ever know ALL of the facts of this case, except for Sean & his victims. I have known Sean for over 10yrs, and he suffers from "terrible demons". I'll stop there. I wish nothing but peace and piece of mind for his victims, their families, and to Sean's friends and loved ones, ESPECIALLY his mother. I hope that this is the "wake up call" that he has so desperately needed for years to turn his life around and learn how to make better choices. He has confessed to this crime, which is the 1st step. He will be held accountable for his actions, and he has NO ONE to blame but himself. To "Mort Feldstein": How DARE you blame the victims of Sean's previous home invasion conviction for ANYTHING! I am appalled at your ignorance, Sir. A terrified, 12yr old babygirl cannot sleep, and that is her MOTHER'S fault? "Mr. Feldstein", my wish for YOU is that you get a clue.

There are a few of you who really need to research drug and alcohol addiction before you run off at your keyboards. Drug and alcohol use are no excuses for any type of behavior, it causes havoc in families, communities, personal and professional lives. Most times the person with the addiction has to fall, and fall hard. Maybe this will be a wake up call for this kid, maybe not. Everyone has to reach their personal bottom to come back to the top. I hope this kid has hit his so that he is no longer a danger to his family and our community. I am glad our Sheriff's officers were able to get this handled quickly, but I feel that we need more of a police presence in all of our neighborhoods to show that we, as a community are not going to tolerate the level of violence that is rising here in Bel Air. I pray for the victim in this case, and his family that they can have peace now that he is off the street, and I hope to God no one posts bail. Let him sit in jail for his crime.

Deep down Sean has a good heart just drugs n pussy took over his life...all u are judging...who's to say he intended to stab dude.if i made the bad choice to break in i wouldn't let someone beat me with a bat....im sorry Sean...if any of u idiots know nothing about the court system dwi,theft?there minor...he will pay as all of us have for our mistakes.

Honestly, just so you guys know... this kid is a known POS with everyone our age. He has drugged girls multiple times at our local bars. People think it is all pills--once you can't afford pills anymore you go to heroin. It is cheaper/ easier to come by. This guy deserves everything he gets. Stop feeling so sorry for him. He wouldn't feel bad if he could use/abuse you like he has everyone he has come in contact with. His mom is an enabler for bailing him out. I hope parents open their eyes to the sketchy kids in this community.

When did he get bailed out of jail for this crime?

Who is"Mam"? Several women have posted.....fyi

Just read the Maryland Judiciary Search for this guy, he's toast this time I suspect.

A trend is a trend until it ends.

This one is headed for conclusion..

Years and years ago I new this kid and ill tell you now he was sober then and he we still a creep! Ive always kept my distance. He was born bad! No hope for him!

I don't know if this has been said already...there are so many comments. But has anyone noticed how the break-ins in the area (Thomas Run and Tudor Manor) have completely stopped since this loser has been caught? I hope they will be able to link him to those as well.

Good news. This worthless piece of dog sh*t plead guilty and took a 30 year sentence. They should have locked his spineless, enabling mother away too.
